Struct SelectPrompt 

pub struct SelectPrompt<'a> { /* private fields */ }

A prompt widget for choosing one option from a list.

SelectPrompt owns the label and options to render, while SelectState tracks the focused option, focus state, and completion status. Render the prompt before routing key events so the state can learn how many options are currently selectable.

When the render area is shorter than the option list, the prompt renders a window around the focused option so the highlighted row remains visible.

Implementations

impl<'a> SelectPrompt<'a>

pub const fn new( label: Cow<'a, str>, options: SelectOptionList<'a>, ) -> SelectPrompt<'a>

Creates a select prompt from a label and an ordered option list.

pub fn with_block(self, block: Block<'a>) -> SelectPrompt<'a>

Wraps the prompt in a Block.

Trait Implementations

impl<'a> Clone for SelectPrompt<'a>

fn clone(&self) -> SelectPrompt<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for SelectPrompt<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'a> Default for SelectPrompt<'a>

fn default() -> SelectPrompt<'a>

Returns the “default value” for a type.

impl<'a> Eq for SelectPrompt<'a>

impl<'a> PartialEq for SelectPrompt<'a>

fn eq(&self, other: &SelectPrompt<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Prompt for SelectPrompt<'_>

fn draw( self, frame: &mut Frame<'_>, area: Rect, state: &mut <SelectPrompt<'_> as StatefulWidget>::State, )

Draws the prompt widget.

impl<'a> StatefulWidget for SelectPrompt<'a>

type State = SelectState

State associated with the stateful widget.

fn render( self, area: Rect, buf: &mut Buffer, state: &mut <SelectPrompt<'a> as StatefulWidget>::State, )

Draws the current state of the widget in the given buffer. That is the only method required to implement a custom stateful widget.
